Flight experiments aimed at studying the transition from the laminar to turbulent flow in the boundary layer on the glider wing at different levels of atmospheric turbulence performed in the 1980s are reviewed. The results are obtained by means of hot-wire measurements and visualization of the flow on the wing surface by the method of sublimating coatings. The transition is found to proceed in several stages: emergence, evolution, and failure of a discrete packet of instability waves in the region of the adverse pressure gradient. The data obtained in the study are compared with the results of similar investigations carried out in a large wind tunnel on the same real glider wing at realistic Reynolds numbers.

大气湍流对滑翔翼边界层流影响的实验研究

回顾了 1980 年代进行的飞行实验，旨在研究滑翔翼边界层在不同水平的大气湍流下从层流到湍流的转变。结果是通过热线测量和通过升华涂层方法对机翼表面流动的可视化获得的。发现这种转变分几个阶段进行：在不利压力梯度区域中不稳定波的离散包的出现、演化和失效。将研究中获得的数据与在同一真实滑翔机翼上的大型风洞中以实际雷诺数进行的类似调查的结果进行比较。
